Precision Casting Process And Its Advantages

1. product qualityCasting high dimensional accuracy, generally equivalent to 6~7 level, even up to 4 levels; good surface finish, equivalent to 5~8 level; high strength and hardness, strength 25~30% higher than sand casting, but about 70% elongation; dimensional stability, good interchangeability; casting thin wall complex castings. For example, the current minimum wall thickness of zinc alloy die castings can be 0.3mm 0.5mm aluminum alloy casting; the smallest cast aperture 0.7mm; 0.75mm is the minimum pitch.2. high efficiencyHigh productivity of the machine, such as domestic j-III 3-horizontal cold casting die casting machine with an average eight-hour 600~700, small hot Chamber die casting machine for every eight hours of die-cast 3000~7000 times;-casting long, a pair of die casting die, die-cast Bell alloy, life can be up to hundreds of thousands of times or even millions; mechanisation and automation.3. the economic effectDue to the precise size die castings, sheet pan, smooth and so on. General mechanical processing no longer used directly, or process is very small, so increase metal utilization, and reduce a lot of processing equipment and work; casting price easy combination die cast with other metallic or non-metallic materials may be used. Saves Assembly time and save on metal.
